A retail company is planning to expand its online presence and wants to use Dynamics 365 Commerce to build a new e-commerce site. They need to ensure that the site can handle high traffic during promotional events and that product catalog updates are reflected quickly. What should they consider?
CDN helps with traffic, and optimizing sync ensures quick updates.
Why this answer
Using a Content Delivery Network (CDN) caches static assets (images, scripts, CSS) at edge nodes, reducing load on the origin server during high-traffic promotional events. Optimizing catalog synchronization (e.g., using incremental syncs and the Commerce Data Exchange) ensures product updates are reflected quickly without full re-indexing, maintaining performance and data freshness.
Exam trap
The trap here is that candidates may think disabling caching ensures fresh data (Option B), but in high-traffic scenarios, caching with proper invalidation (e.g., using cache tags or TTLs) is essential for both performance and data freshness.
How to eliminate wrong answers
Option A is wrong because increasing the channel database size does not improve traffic handling or update speed; it only addresses storage capacity, not performance under load. Option B is wrong because disabling caching for product pages would force every request to the origin server, increasing latency and server load, which is counterproductive for high-traffic events. Option D is wrong because limiting the number of products in the catalog is a business constraint, not a technical solution for scalability or update speed; it would reduce catalog breadth unnecessarily.
